To all whom t may concern.'

Be it 'known that I, FLETCHER CH-Anwon,

a subject of the King of Great Britain, refv f v l tape form from thegbeam or beams and vdistributed diagonally tothe drawing roll-1 siding at Fieldhouse Mill, Rochdale, in the county of Lancaster, England, have invented ,new n and useful lmprovementsi` in Frames for Doubling Yarns, (for which l have made application in Great Britain April 20,1917, Fatent No. 106,978,) of which the following is a specification.

My invention relates .to improvements in frames for doubling yarns from warpers beams. i

It is well known that doublingortwistn ing from one or more warpers beams has been carried on previously for preparing yarns in the manufacture of heavy counts for twines, netting,duclrs, and other coarse or heavy fabrics. y Y

In such` cases it has beenv customary to support the warpers beam, or each beam, in

a creel upon a drivenV drum and to deliver..

the yarns from the warpers beam as it is rotated by surface contact with its' driving drum but this method has been unsatisfacT tory because the threads as delivered from 4the beam are uneven in'tension thereby causing more or less corkscrewed yarn and, further, the dividing anddistribution of the threads to the spindles are the cause of `much unequal tension owing to the spindles being disposed over a widerv area than the width of the warpers beam.V

To overcome these defects it has been proposed to mount the warpers beams or beam upon stands and pull olf the yarn lby means of top and bottom lines ofI drawing rollers but this method also has encountered difficulties in the distribution of the threads and in limiting the doubling to one side of the frame owing to the necessity of delivering the yarn in as nea-r a straight line as possible to the spindle.

According to my present invention pro-A drawing .Y rollers-iink *the following novel manner- Y t The threads are drawn oil1 vertically in ers and thence to thespindles-by mea-nsof suitable guides and carriers overthe'wider distance occupied by the spindles.

rlhe first set ofY guides areplacednear and preferably belowthe beam in order to assemble the required numberl of threads for each spindle in `tape form and adjustable carriers are arranged to guide and carrythe` tapes obliquely to, their respectivespindles it is .necessary to show for the purpose of `7'5 explaining my invention.

Figs a and 5 are detail-views of asuit-v doubling vof able form of thread guides, Fig. 4 showingl-r the guidesV used on the leftfand'Fig'. 5 theV guides used on the righthand side ofthe machine.k

diate thread guides or carriers; g thread 90 to the driven drawing rollers z. which are l v j guides for guiding and delivering the ends supported and driven in the known Inanner; i thread guides beyond the drawing rollers; jthe travelers; and 7c the bobbinson l' which ythe doubled and. twisted ends.Y are wound in the usual way. l l v Beginning at the middleof the warpers beam a oro the threads for each spindle, two or more ends as the case may be, are drawn o' in tape form from each warpers beam and taken ,vertically downward through the rst of say the right series of thread guides e and then diagonallyto the first thread guide g of the right hand series Y sov` `ln these views, @,yafdesignate theitwo, warpers beanis, v.the creel in which they l are supported: o the threads, ka rail, pref,

through the drawing rollers L, through the corresponding thread guide z' and thence to the traveler j by which it is twisted and wound upon its bobbin'lc or equivalent part. ln like manner each succeeding group'V of Vends is drawn oil'l thewarpers beam and led through the successive thread guides in tape vand e' are similarly or vequivalently formed 'I and pla Y ed sotas to maintain each group of ends vllat and prevent them eoiling up or corlrseiewing.

After, sayeight or nine spindles from theV Acenter on the right hand side Vhave been fed, the angle for the next group of ends becomes too wide for the threads to be led directly to the drawing rollers without an intermediate support and therefore the remaining series of threads on the right hand side they leave their guides e are passed ozeiround pins or equivalent guides or carriers inountedon the adjustable rail f before Y being taken to the guides g and through the b ein@ set drawing rollers 7L.

The threads for theleft hand series of guides e are selectee from Athe middle of the warpers and led through guides to the sjindles in lilre manner the thread 1 i Jo a guides o; the lei-t hand side of the frame as indicated in Fig. 5 so as to give double bearing for the ends and maintain e in tape form as already specilied. It will be readily understood that the inachinos may have a single warpers beam and any suitable number of spindles on one side only instead of two beams and spindles on both sides as shown; that fliers instead of rings and travelers may be employed for pghatl claim as my invention and dGS.

to secure by Letters lPatent is y l. The 'combination withV a warpers beam doubling frame, of a `plurality of. spindles, drawing rollers parallel with said beam, means for drawing olf groups of threads vertically in tape form from said beam, and means for distributing said groups diago nally to the drawing rollers and thence to the spindles overV the wider distance'oecupied by the spindles, while maintaining the groups in 'tape form. Y Y

2. ln a doubling frame, in combination a warperls beam; a line of Ydriven drawing rollers parallel with said beam; a series of kspindles extending beyond the width ofthe beam, and adjustable thread guides'between said beam and spindles to distribute diagon ally to its respective spindle each group of threads drawn in tape form from the beam vsubstantially as herein set forth. Y

ln testimony whereof I have signed my name to this specification.
